21. Flotation in turbulent waters: Heteropterid bugs

"Among the most superficially aquatic and numerous insects of freshwater areas are various Heteropterid bugs, such as pond-skaters, water-measurers and water-crickets. lnsects like these seldom even get their feet wet since they are able to stride...

22. Trenches gather water: flying saucer trench beetle

"A third method involves uptake of free water directly from fog-moistened sand. The most elaborate procedure is used by the genus Lepidochora (Seely and Hamilton, 1976) (Fig. 3 c). These flat, circular, short-legged beetles construct a shallow tre...

23. Fog-catching materials

Oxford biologist Dr. Andrew Parker and Dr. Chris Lawrence of QinetiQ were studying tenebrionid (Stenocara) beetles in the barren Namibian Desert when they discovered the shell of these insects has a bumpy surface texture. Further research show...

24. Channels protect from freezing: goldenrod gall fly

"The movement of water and small solutes is integral to the survival of freezing and desiccation in insects...Recent evidence suggests that aquaporin (AQP) water channels play critical roles in protecting cells from osmotic damage during freezing ...

25. Deciduous trees produce more soil water: oaks

"Will any forest tree work the same on a given site? Are trees completely interchangeable? The questions hinged on whether trees vary in their capacity for water interception and transpiration. To get answers, loggers clear-cut mature hardwood for...

26. Water-repellent ship coatings

Structural design of water fern leaf surfaces may be mimicked to create superhydrophobic coatings for ships and other technological surfaces. Such coatings could significantly reduce friction and drag forces on ships, thus decreasing fuel consumpt...

27. Body buffers thermal variations: sea star

"The body temperature of ectotherms is influenced by the interaction of abiotic conditions, morphology, and behavior. Although organisms living in different thermal habitats may exhibit morphological plasticity or move from unfavorable locations, ...

29. Water collection cools hive: honeybee

"Honeybee colonies collect water for two reasons, related to different types of weather: for cooling of the brood area by evaporation on hot days, and for feeding the larval brood when foraging is limited on cool days (Lindauer, 1955; Seeley, 1995...

30. Leaves retain air films underwater: water fern

"A novel mechanism for long-term air retention under water is found in the sophisticated surface design of the water fern Salvinia. Its floating leaves are evenly covered with complex hydrophobic hairs retaining a layer of air when submerged...
